.Specification of Letters Patent No.` 26,406, datedDecember 113,118559. i

To all 'whom it may concern: t t

Be it known that I, A. R. BARTRAM, of Redding, in the county of `Fairfield and State of Connecticut, have invented anew and useful Improvement in Wheel-Vehicles; i I and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which-- Figure l, is a front view ofthe portion of a wheel vehicle which refers to my improvement. Fig 2, is a plan or top View of the same. Fig. 3, is a transverse section of the i same, taken in the line zc, Fig. l. y

i Similar letters of reference indicate corresponding parts in the several figures( This invention relatesto a `novel mode of attaching the front bolster of the vehicle to the front axle substantially as hereinafter described, whereby a positive or rigid attachment of the thills or draft pole to the front axle is obtained, and all unnecessary play and rattlehitherto consequent `on said attachment avoided and a more `durable and desirable vehicle obtained.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents the front axle of a vehiclef and B, the front bolster. The axle may be constructed in the usual or any suitable way and its wheels attached to it in any of the known ways, the present invention depending on no peculiarity of construction in either of the above named parts.

The bolster B, may be wholly of cylindrical form, at all events, two portions of it a, at equal distances from its ends must be of cylindrical form in order to receive sleeves C, C, which may turn freely thereon. These sleeves are of metal and they are at the upper ends of uprights b, b, which areat the ends `of a bar c. The sleeves C, C, are retained in proper place on the bolster, that is to say, prevented from moving longitudinally thereon by means of `metal collars cl, cl, which are permanently attached to the bolster at the outer sides of the sleeves.

The sleeves C, C, uprights b, and bar c, may be of malleable cast iron and the center of the bar c, has a circular plate d', recessed at its under side to receive a circular plate e,

attached to the axle lA, :a pin or bolt f, passing through the centers of the plates (if, e, see Fig. l1, the above parts forming what@ is generally termed afl`circlepla`te. i i The plate e, is attached to or forms. part of a barg,"whic`hispermanently"sev cured to the upper: surface: of the axle A, at its central part` by clips` h,ftheftwo bars c, g, being one over-,tithe other when 1th t bolster and axle are in] the same pla-ne.` 1

D, D, represent thills or shafts which may be of usual constructions1 `'.llhesethills `jor shafts areattached at theirlback ends fd' rectly and rigidly to the axle so that as th thills or shafts are raised` andlowered the f axle A, will turn or swing on the bolster B, in consequence of the attachment `formed by 3 thesleeves 0,0. y y From the above description it wllbe seen that a good circle plate may be used andnin terposed between the axle andbolster and a perfect bearing obtained equally uso, asin` vehicles of ordinary constructionsand, at the -same time in consequence ofthe attachment of the axle A,`to.the bolster B, the axle as before stated,1 is allowed ftol swing and admit of a positive or "rigid attachmel of the thills or draftfpole to 1t. y y I am aware that wheel vehicles have bee previously constructed with y the thills `a tached permanently and rigidly to the `fron axle, but, so faraskI amawareno means y have been devised to` admit of a `swinging of said axle with aI properconnection` toits bolster. I believe that a loose king bolt has only been used, the turningfof the axle depending on the play allowed the` bolt t when fitted in the axleQ y `It will readilybe seen that this arrangementmust be attended with great wear anda `rattle,whichis `extremely unpleasant anda greatobjection to a pleasure vehicle. i i. 1. t I would remark that `the ordinary elliptic or the longitudinal side springs may be used. If the elliptic springs are used, `the ordinary perch coupling would be required.

I do not claim theattaching of the thills y or draft pole of a wheel vehicle permanently and rigidly to the front axleffor' this has` been previously done,"but, i i

I do claim as new and desire to secure by" Letters Patent, l t i t .t t
